    Abstract: An injection device includes a housing having an internal volume and a viewing portion. A movable seal is disposed in the internal volume and is movable from an initial position to an injection end position to urge a drug product out of the housing. An indicator assembly is disposed in the internal volume and includes a dose end indicator. The indicator assembly is biased from a dose remaining position toward a dose end position where the dose end indicator is visible through the viewing portion. A release mechanism releasably holds the indicator assembly in the dose remaining position and is linked to the movable seal such that the movable seal reaching the injection end position causes the release mechanism to release the indicator assembly to the dose end position.
